This is a 20 dots kolam with a pattern as follows 20 dots in 12 columns and reduced to 12 dots on either side. The dot pattern is given below.
The final output may be confusing as the swirls on the outer may give an illusion of a 20×20 grid.. I have given a sketch of the kolam below, Hope this is clear to understand. Colour as per your wish. The month of colours, The Margazhi is on the way, so this is an apt kolam for the season.
